Well Hello There: New T-Rex Like Dino Discovered In Utah

new-dino-species-discovery.jpg

A new (but still long dead) t-rex like dinosaur species has been discovered in Utah, leading paleontologists to believe that large, bipedal carnivorous dinos were much more widely distributed than previously thought. Which is great news because no matter where my time machine lands I should still be able to find a girlfriend.

"This dinosaur was a colossal predator second only to the great Tyrannosaurus rex and perhaps Acrocanthosaurus in the North American fossil record," said Dr Lindsay Zanno from the North Carolina Museum of Natural Sciences and the Field Museum of Natural History, the lead author on the paper published in the journal Nature Communications.


The prehistoric giant is named Siats meekerorum. The genus name, Siats, refers to a cannibalistic monster from the mythology of the Ute Native American people. Its specific name acknowledges the Meeker family for their support for early career paleontologists at the Field Museum.

Siats meekerorum was over 9 meters long and weighed more than 4 tons. Despite its large size, the dinosaur is not a close relative of Tyrannosaurus rex and other tyrannosaurs.

Are you thinking what I'm thinking? "You would marry it." Could you imagine laying in bed playing with the little fuzz on its arms while you both drift off to sleep? "No." Well try. "It's not working." Try harder. "I don't want to sleep with a dinosaur." Are you just saying that because you know I want them all? "...Yes?" You're so sweet to me!

    That's pretty neat.

    Why am I suddenly hungry for some chicken?

  • Anderson Monteiro

    OMG! This one has fur!!! Wait.. how come? With only bones, now you can know for sure that dino's skin color, eye color and even that it has fur and also fur color!!! Amazing! #sarcasm#

  • disqus_k2QxOV9H7Z

    Colors are all by the artist or else all dino images would be grey. "Fur" probably are some sort of primitive feathers. Since some dinos related to it had feathers it is a good guess that this one would have it too.

  • Anderson Monteiro

    As you said, still a wild guess, even feathers cannot be proved by bones, unless the bone was hallow then the dino would also fly. My sarcasm is about that, they take for granted what is only a wild guess.

  • Sergeant_Poop

    You seriously think dinosaurs having feathers is a wild guess?

  • Anderson Monteiro

    Sort of, the claims of feathers are looking more and more dubious. In one of the most famous claimed feathered dinosaurs, Sinosauropteryx, the evidence indicates that the filaments were not separate feathers, but support fibres for a unified structure like a crest. Also, the death posture indicates suffocation, and careful analysis of the normal decay process of animal carcasses in nature shows that it must have been buried completely within a few days at most.

    Some fossils had evidence for feathers so dinos related to them probably had them too. Did you know that chickens are closer relatives to A T-Rex than a stegosaur?

    New research shows that birds lack the embryonic thumb that dinosaurs had, suggesting that it is “almost impossible” for the species to be closely related. A team led by bird expert Alan Feduccia, chairman of biology at the University of North Carolina, studied bird embryos under a microscope, and published their study in the journal "Science".

    A team led by John Ruben, a respiratory physiology expert at Oregon State University in Corvallis, analysed fossil outlines of Sinosauropteryx’s internal organs. Its ‘bellowslike lungs could not have evolved into the high-performance lungs of modern birds. Indeed, birds have a complicated system of air sacs which keep air flowing in one direction through special tubes (parabronchi) in the lung, and blood moves through the lung’s blood vessels in the opposite direction for efficient oxygen uptake,an excellent engineering design.

    Also, Ruben and ancient bird expert Larry Martin believe that the so-called ‘feather’ traces are actually frayed collagen fibres beneath the skin. Feather expert Alan Brush, University of Connecticut, Storrs, points out that they ‘lack the organization found in modern feathers.

    It is the scientific consensus that many dinos had feathers and are related to birds. Even your claims have been counter argumented or disproven by other scientists.

    Embryologists and some paleontologists who oppose the bird-dinosaur link, have long numbered the digits of birds II-III-IV on the basis of multiple studies of the development in the egg. This is based on the fact that in most amniotes, the first digit to form in a 5-fingered hand is digit IV, which develops a primary axis. Therefore, embryologists have identified the primary axis in birds as digit IV, and the surviving digits as II-III-IV. The fossils of advanced theropod (Tetanurae) hands appear to have the digits I-II-III (some genera within Avetheropoda also have a reduced digit IV). If this is true, then the II-III-IV development of digits in birds is an indication against theropod (dinosaur) ancestry. However, with no ontogenical (developmental) basis to definitively state which digits are which on a theropod hand (because no non-avian theropods can be observed growing and developing today), the labelling of the theropod hand is not absolutely conclusive.
    Paleontologists have traditionally identified avian digits as I-II-III. They argue that the digits of birds number I-II-III, just as those of theropod dinosaurs do, by the conserved phalangeal formula. The phalangeal count for archosaurs is 2-3-4-5-3; many archosaur lineages have a reduced number of digits, but have the same phalangeal formula in the digits that remain. In other words, paleontologists assert that archosaurs of different lineages tend to lose the same digits when digit loss occurs, from the outside to the inside. The three digits of dromaeosaurs, and Archaeopteryx have the same phalangeal formula of I-II-III as digits I-II-III of basal archosaurs. Therefore, the lost digits would be V and IV. If this is true, then modern birds would also possess digits I-II-III. Also, one research team has proposed a frame-shift in the digits of the theropod line leading to birds (thus making digit I into digit II, II to III, and so forth).

    In 2011, samples of amber were discovered to contain preserved feathers from 75 to 80 million years ago during the Cretaceous era, with evidence that they were from both dinosaurs and birds. Initial analysis suggests that some of the feathers were used for insulation, and not flight. More complex feathers were revealed to have variations in coloration similar to modern birds, while simpler protofeathers were predominantly dark. Only 11 specimens are currently known. The specimens are too rare to be broken open to study their melanosomes, but there are plans for using non-destructive high-resolution X-ray imaging.
